Název v původním jazyce

Collisions of Slow Polyatomic Ions with Surfaces: Dissociation and Chemical Reactions of CD5+, CD4+, CD3+ and Their Isotopic Variants on Room-Temperature and Heated Carbon Surfaces.

Popis výsledku v původním jazyce

Interaction of small hydrocarbon ions, CD3+, CD4+, CD5+, and their isotopic variants CHn+ and (CHn+)-C-13 (n = 3, 4, 5), with room-temperature and heated carbon (highly oriented pyrolytic graphite, HOPG) surfaces was investigated over the collision energy range 16-52 eV. Mass spectra, translational energy distributions, and angular distributions of product ions were determined. Collisions with room-temperature surfaces showed both surface-induced dissociation of the projectiles and chemical reactions with the surface material. All projectiles showed formation,of C2X3+ (X = H, D) in interaction of the projectiles with terminal CH3-groups of surface-adsorbed hydrocarbons and a small amount of C-3 product ions, and collisions of CD4+ led, in addition, toCD4H+ by H-atom transfer from surface hydrocarbons. The surface collisions were inelastic with 41-55 of incident energy in product-ion translation (incident angle 60degrees with respect to the surface normal).
